"Flappy Bird
was designed to play in a few minutes when you are relaxed,"
Nguyen told Forbes reporter Lan Anh Nguyen. "But it happened to
become an addictive product. I think it has become a problem. To
solve that problem, it's best to take down Flappy Bird. It's gone
forever."

The Forbes
reporter noted that the 29-year-old game maker looked "stressed"
and smoked a number of cigarettes during the interview, which was
less than one hour long.

Nguyen also
said the app was disturbing his personal life. Forbes says he
yanked the app due to "guilt."

"My life has
not been as comfortable as I was before," Nguyen said. "I
couldn't sleep." He plans to make more games and leave his other
two hits, Super Ball Juggling and Shuriken Block, in app stores.
But if players get too addicted, Nguyen says he'll yank those
too.

What will
Nguyen's next game be? That isn't clear, although the Forbes
reporter caught Nguyen doodling monkeys.
